    Hello.
    I recently downloaded the Unity Hub application, but when I attempt to download and install any of the betas versions, the download goes fine (I guess, since downloading something is harsh with my Internet, 300 Kb/s), but when it comes to installing, it instantly shows the "Installation failed".
    In the components list, I diabled MVSC, since I already own MonoDevelop.

    Hi,
    Sorry to hear you are having troubles installing the editor.

    Can you try installing only the editor first ?
    If all goes well, could you try adding the required components after?

    Thank you for your help.

    I had the same issue as the op. I solved it by following your instructions but I had to close the hub application then restart it for your instructions to work and it would stop working after every component or 2 that were installed; so I had to close out of the hub app several times and repeat the process several times until everything was downloaded and installed.

    Sometimes the download would fail, sometimes the install would fail and it would say, "the file was corrupted."
    I restart the hub application, add one component at a time til it breaks again, then repeat the process until all components downloaded and installed successfully.

    Hello @HouseHoStudio and @HanSolar.
    Can you report a bug in the Hub, please? You can now report a bug by right-clicking on the tray menu icon and selecting "Report a bug".

    Thank you

    I just discovered that if you set Windows Security "Exploit protection" settings "Force randomization for images (Mandatory ASLR)" to ON, that the Unity Hub installer always fails with this error. Turning it OFF (which it is by default) fixes the issue.

    Glad it helped. I was just experimenting one day, and when things started failing mysteriously, I was a little bit annoyed.

    Hello, for the current version of the hub, if the machine goes off or sleep or if the internet stops during installation, the whole process is aborted. It will be fixed soon but for now, keep an eye on your computer while installing the unity editor to check for issues.

    I used unity some time ago, and now im motivated to make games. I install unity hub and the intallation just stuck around 79.5-80%. I have tried a lot of thigs, even reinstall my windows and nothing helps. Even if i skip install wizard and i chose what version i want, the installation goes 100% and then gives me the same error, that i couldn`t install that version of unity. Can anyone help me? Thank you! :)

    @driAn14 ,
    I see you are using the new user onboarding flow... I cannot investigate on why it's not working without the logs, so if you can report a bug via the hub bug reporter (from tray menu, cf the screenshot), it will be easier. Also, since you have already used unity, you can uninstall the hub and install the normal setup (not the new user onboarding) via this link https://unity3d.com/get-unity/download (to unblock yourself because the latest builds of unity editors need the hub to be installed).

    For anyone still facing this issue, here's how I fixed mine.

    If you have any instances of Hub running, first close them. Even from task manager. Then when installing the editor of your choice, install only the editor with no additional modules. Uncheck all the modules and install the editor. After editor installation, you can add all the necessary modules.

    This worked for me. Hopefully works for you as well. Try it out and let me know.

    This fixed the "download failed - incomplete or corrupted download file" error, thanks.
    I also noticed I had it right after waking up my laptop, so I increased the delay before going to sleep.
    @ksc_3899 's method can also help, since downloading the core editor first will make download faster and reduce odds to sleep while installing. I don't know if the error can occur while installing additional modules.

    I had this problem, after accidentally deleting the Unity hub.
    I Went to "Control Panel' and saw that Unity hub was still there, even though it wasn't installed on my computer anymore.
    I uninstalled it again from the Control Panel, it told me it was already uninstalled and asked if I wanted to remove it from the Control Panel. I picked yes, removed it, then reinstalled.
    That worked for me.

    I tried installing from command prompt as Administrator and it says "access denied". I right clicked on properties of the full download exe and noticed a message with a tick beside it.
    "This File came from Another Computer and might be Blocked :) I unchecked it and now Unity 2019.3.1.14f1 is finally installing!
